Toluene degradation in Pseudomonas putida KT2440 pWW0 plasmid is subjected to catabolite repression. Pu and P(S1) promoters of the pWW0 TOL plasmid are down-regulated in vivo during exponential growth in rich medium. In cells growing on minimal medium, yeast extract (YE) addition mimics exponential-phase rich medium repression of these promoters. We have constructed and tested mutants in a seri...
AIM To compare surgical and oncological outcomes after pancreaticoduodenectomy (PD) in patients ≥ 75 years of age with two younger cohorts of patients. METHODS The prospectively maintained Institutional database of pancreatic resection was queried for patients aged ≥ 75 years (late elderly, LE) submitted to PD for any disease from January 2010 to June 2015. We compared clinical, demographic a...
Mortierella alpina (M. alpina) is well known for arachidonic acid (ARA) production. However, low efficiency and unstableness are long existed problems for industrial production of ARA by M. alpina due to the lack of online regulations. The aim of the present work is to develop an online-regulation strategy for efficient and stable ARA production in industry. The strategy was developed in 50 L f...
Pleurotus have an easy cultivation and are excellent sources of proteolytic enzymes. The aimed was evaluate the mycelial growth extracellular protease activity ostreatoroseus. mushroom grown on potato dextrose agar (BDA) with yeast extract (YE) 0.5% (w/v). radial velocity (RCV) density occurred different media containing (w/v) YE: Potato Dextrose (BDA), GYP (glucose, peptone), malt (MEA), purpl...
To determine if threatened brown bear (Ursus arctos) populations of Montana and Wyoming have lower levels of genetic variation than other North American populations, we examined mitochondrial DNA (mtDNA) and nuclear microsatellite DNA diversity in 220 brown bears from 5 areas: Kodiak Island, Alaska; Kluane National Park, Canada; Eastern Slope of the Rockies (East Slope), Canada; Yellowstone eco...
The ability of the central nervous system to cope with stressful conditions was shown to be dependent on proper T-cell-mediated immune response. Because the therapeutic window for neuroprotection after acute insults such as stroke is relatively narrow, we searched for a procedure that would allow the relevant T cells to be recruited rapidly. Permanent middle cerebral artery occlusion was induce...
